A radius-forming dressing roll (32) having a frustoconical working region (48) and an adjoining concave-toroidal working region (49) is mounted on the dressing spindle (30) coaxially to a dressing disc (31). In a first step, the flanks (42, 43) of the grinding-worm thread are profiled with the disc (31). After the dressing spindle (30) has been pivoted, the two tip radii (46, 47) and the cylindrical outer circumference (45) are profiled with the dressing roll (32). With little resetting effort and high flexibility, the method permits profiling with short dressing times.
